Each gap is to the same group, grades and subject: in Walnut Valley Unified, and across California. ■ Green: a group that is behind statewide does much better here, by 10 points or more and more than twice the margin of error.

White students and students of two or more races: fewer than 30 tested here. No published rate here for Black or African American, American Indian or Alaska Native, Pacific Islander, homeless and military-family students and foster youth. That can reflect privacy rules or small numbers; it isn’t evidence of a gap. This table covers groups by income, race or ethnicity, language and disability; girls and boys aren’t split out.

How many students from Diamond Bar High go to UC?
In fall 2025, 194 Diamond Bar High graduates enrolled at University of California campuses, universitywide. That figure can't be split into a per-campus sum — students apply to several UC campuses at once, so campus-level counts don't add up to the universitywide total. UC is one destination among many: this says nothing about graduates who chose a CSU, a private college, a community college, or work, and it is a count, not a rate or a ranking. Data source: University of California Office of the President (UC Information Center), fall 2025 admissions cycle.

From 2025–26 reporting, California calls Level 3 Proficient and Level 4 Advanced (formerly Standard Met and Standard Exceeded). “Proficient or Advanced” combines both levels in the 2025–26 results shown here. California's level descriptions.

That cohort includes all students in the current four-year graduation cohort plus only Prepared fifth-year graduates from the prior cohort. In 2025 the pathway accepts two qualifying AP exams, two qualifying AP courses, or a combination of one of each in different subjects.

CDE's overall Prepared rate is this version's 20% high-school college-readiness score factor. The school rate is 520 of 670 CCI students, not the AP-only pathway or A–G completion rate. The California figure is CDE's statewide CCI student cohort, not an average of SchoolScope's comparable high schools or the SchoolScope school-rank pool.

CDE reported all-students (TA) school rates for 2025 and 2026; the change is 2026 minus 2025 in percentage points.

Each year names its school year end (2026 = 2025–26). “Students with scores” is the subject-specific rate denominator; ELA and Math counts must not be added. The 2015–2018 rows were checked against CDE’s original research files. The 2015 and 2016 files report whole percentages; later rows round to one decimal here. Older stored rows from other years still need independent original-file re-verification. A dash is unavailable, not zero. Before spring 2026, Advanced was reported as Exceeded and proficient or advanced as met or exceeded.

Source: UC admissions by source school. Dated fall first-year UC applicants, admitted students, and enrollees. GPA is each group's mean weighted, capped high-school GPA for 10th/11th-grade college-preparatory courses. SchoolScope leaves GPA unavailable when several CEEB codes contribute rather than combining their means. Masked means no numeric bound; — means unavailable, and a reported zero remains zero. For missing or masked counts, never assume zero or a positive hidden value. A + marks a partial SchoolScope sum of observed counts, not a complete total; missing contributions may be zero. No admit rate is computed here. Complete, matching counts can support a historical descriptive rate, but do not establish a school's effect or predict individual chances. Series shown from 2014.

How the California mean was selected

SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.

Selected General Fund operating costs · FY 2024–25 · SchoolScope calculation
Instruction 59%Instruction support 10%Student services 13%Administration 6%Buildings & maintenance 11%Other 1%

SchoolScope groups district-level CDE SACS UserGL actuals from Fund 01, using operating objects 1000–5999 and excluding retiree benefits, food and community services, facilities acquisition, other outgo, and nonagency goals. These shares use that filtered total; they do not exactly break down CDE's official current expense per ADA above. The school-level ESSA figure uses a separate source.
